Description

[Detailed Description of the Invention] Technical Field The present invention relates to an apparatus for producing postcards and envelopes from printed continuous forms.

Conventional technology Print out postcards using a computer,
In order to make efficient use of printers when manufacturing envelopes, a method has been adopted in which postcards and envelopes are manufactured by using a common continuous form during printer processing and processing after printing. It is known that In this case, these forms are coated with glue in advance, and after being printed out, the forms are processed into postcards and envelopes by heating, pressurizing, or humidifying the forms while folding them.

In addition, glue is applied partially to the necessary parts of the printed continuous form, which is then folded to form a continuous form of postcards and envelopes, which are then cut to produce individual postcards and envelopes. However, when continuous sheets of paper meander during gluing and folding operations, not only does the folding misalignment occur at the folding section, but also the position relative to the gluing roller shifts, making it difficult to fold. If you glue a part, the glue will protrude from the perforation because this part has perforations for folding.
They may adhere to the folding pieces and rollers of the device and cause dirt, or the pin feed holes of the pin tractor may be misaligned due to misfolding, resulting in defective products. In addition, paper that is glued has an unstable balance, and continuous forms have perforations for cutting single pieces at equal intervals perpendicular to the flow direction of the form. If an attempt is made to forcefully fold the paper at the cutting edge, buckling is likely to occur at the cutting perforation, making it difficult to handle continuous forms and making it difficult to properly glue and fold them.

Purpose This invention prevents continuous forms from meandering, and
By guiding folding after gluing, gluing,
An attempt was made to make it possible to easily manufacture postcards and envelopes by ensuring that the folding process is performed accurately, improving the shortcomings of the conventional method, and applying glue to continuous forms after they are printed out while folding them. It is something to do.

composition This will be explained below with reference to the drawings.

The drawings show an apparatus for manufacturing continuous postcards and continuous envelopes according to the present invention, in which Fig. 1 is a side view, Fig. 2 is a perspective view, Fig. 3 is a plan view of the tension bar, and Fig. 4 shows the conical piece being moved from side to side. FIG.

This device is provided with a paper feed tray 3 on the lower side of the machine casing 1 for placing folded continuous forms 2, and the continuous forms 2 pulled out from this tray are guided by guide rollers 4 provided at an upper position. Then, one axis 5 below this
A pair of two shafts 5 and 6 that can be swung around the fulcrum, and
Guide pieces 7, 7 that regulate the left and right positions of continuous forms
The lower shaft 6 is attached to the tension bar 8 formed by fitting the
After guiding it between the two axes from the bottom of the glue pot 9
The liquid glue passes between the gluing roller 11 supplied via the pick-up roller 10 and the pressure roller 13 which can swing around the lower spindle roller 12 as a fulcrum and is guided to the upper guiding roller 14. It is configured. At this time, the continuous form that has passed through the tension bar 8 is transferred to the support roller 12 and the pressure roller 1.
3, the gluing roller 11 and the pressing roller 1
You will be guided between 3 and 3. Note that the amount of glue that adheres to the glue roller 11 is adjusted by the doctor 15.

The continuous form 2 pulled out from the paper feed table 3 is given tension by the shaft 6 which is about to rotate downward about the shaft 5 at the tension bar 8 portion, and at the same time, the continuous form 2 is applied with tension by the guide piece 7 provided so as to be adjustable left and right. ，
Gluing roller 1 while its left and right position is regulated by 7.
1 and the pressing roller 13, the pressing roller 13, which is controlled by appropriate signals, acts to press the continuous form against the gluing roller 11, so that the continuous form 2 is glued. It's summery. Furthermore, if the tension on the continuous form increases,
Since a force is generated in the pressure roller 13 in the direction of separating it from the gluing roller 11, it not only becomes easier to adjust the pressing force of the press roller 13, but also the position of the pressure roller 13 relative to the gluing roller 11 can be adjusted. Alternatively, by moving the pressing roller 13, it is also possible to bring only the continuous forms into face-to-face contact with the gluing roller.

A folding guide shaft 17 is provided diagonally above the guide roller 14 in parallel with conical pieces 16, 16 that are inclined toward the outer end and are fitted on the left and right sides. It is bent inwardly and pulled upward to be folded in half, and the center line of the continuous form is guided to be sandwiched between the folding pieces 18 provided perpendicularly to the folding guide shaft 17. two guide rollers 19 which are provided with folds and are freely rotatable and are provided orthogonally to the guide rollers, etc.;
completely folded in.

The continuous form folded in this way is provided in a state perpendicular to the gluing part, and is made up of two sets of an upper roll 20 with a partial notch in the longitudinal direction and a lower roll 20 without a notch. The applied glue portion is adhered by the press roll section 21 provided with two sets of.

What has been explained above is how to apply glue to a continuous form and fold and collate it in half.The mechanism up to this point is an independent device, and then a well-known buster (a paper feeding device using a marginal punch, a marginal part slitter) is used. A postcard or an envelope shape may be obtained by connecting two devices (consisting of a bursting device and a bursting device that performs separation using horizontal perforations), or they may be constructed integrally.

Effects In this invention, we are trying to manufacture postcards and envelopes by folding the continuous forms while applying glue after printing them out, so if we apply glue to the continuous forms in advance before printing. like,
Not only is there no restriction caused by the printer's printing method, fixing method, etc., such as glue adhering to the printer head, but the pressure roller 1 is equipped with a tension bar 8 with a guide frame and a spindle roller 12.
3. By providing the folding guide shaft 17 with a conical piece, accurate gluing and folding can be performed under appropriate tension. Also, as in the past,
If there is no doctor or if the pick-up roller is equipped with a doctor, the amount of glue will vary depending on the speed, and the amount of glue will increase overall, which will cause problems such as poor drying of the glue and curling of the processed product. However, since the doctor is provided facing the gluing roller, the amount of gluing (glue film thickness) can be kept to the minimum necessary, and the glue drying state after processing can be maintained in a good condition. Furthermore, since the product is pressed immediately after folding in half, the amount of glue can be reduced, and the drying and curling state of the product can be improved.
